    Comparison confidence intervals are very roughly estimated from typical standard errors in MCAS raw scores 
    extrapolated to average CPI measurements. If one CPI value falls within 
    the comparison confidence interval of another CPI value we may not reliably claim
    the measured achievement levels are different. (Make comparisons among CPI values at the same grade level.)
